PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the AdvanceTracsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the AdvanceTrac system.Install any aftermarket stereo loudspeakeras far as possible from the front centerconsole, the tunnel, and the front seats inorder to minimize the risk of interfering withthe AdvanceTrac sensors. Reducing theeffectiveness of the AdvanceTrac systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theAdvanceTrac system is an indication thatat least some of the tires have exceededtheir ability to grip the road; this couldreduce the operator’s ability to control thevehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your AdvanceTracsystem activates, SLOW DOWN.
The AdvanceTrac with Roll StabilityControl system helps you keep control ofyour vehicle when on a slippery surface.The electronic stability control portion ofthe system helps avoid skids and lateralslides and roll stability control helps avoida vehicle rollover. The traction controlsystem helps avoid drive wheel spin andloss of traction. See Using TractionControl (page 165).

•When stopped in congested orheavy traffic during hotweather, place the gearshift inposition P to aid engine andtransmission cooling and tohelp A/C performance.
•Turn off the speed control withheavy loads or in hilly terrain.The speed control may turn offautomatically when you aretowing on long, steep grades.
•Shift to a lower gear whendriving down a long or steephill. Do not apply the brakescontinuously, as they mayoverheat and become lesseffective.
•If your transmission is equippedwith a Grade Assist orTow/Haul feature, use thisfeature when towing. Thisprovides engine braking andhelps eliminate excessivetransmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdvanceTrac with RSC, thissystem may turn on duringtypical cornering maneuverswith a heavily loaded trailer.This is normal. Turning thecorner at a slower speed whiletowing may reduce thistendency.
•If you are towing a trailerfrequently in hot weather, hillyconditions, at the grosscombined weight rating (or anycombination of these factors),consider refilling your rear axlewith synthetic gear lubricant (ifthe axle is not already filledwith it). See Capacities andSpecifications (page 301).
•Allow more distance forstopping with a trailerattached. Anticipate stops andbrake gradually.
•Avoid parking on a grade.However, if you must park on agrade:
1.Turn the steering wheel topoint your vehicle tires awayfrom traffic flow.
2.Set your vehicle parking brake.
3.Place the automatictransmission in position P.
4.Place wheel chocks in frontand back of the trailer wheels.(Chocks not included withvehicle.)
Your vehicle may be equippedwith a temporary or conventionalspare tire. A "temporary" spare tireis different in size (diameter orwidth), tread-type (All-Season orAll Terrain) or is from a differentmanufacturer than the road tireson your vehicle. Consultinformation on the tire label orSafety Compliance label forlimitations when using.

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.

GENERAL INFORMATION
Notice to utility vehicle and truckowners
WARNINGS
Utility vehicles have a significantlyhigher rollover rate than other typesof vehicles. To reduce the risk ofserious injury or death from a rollover orother crash you must avoid sharp turns andabrupt maneuvers, drive at safe speeds forthe conditions, keep tires properly inflated,never overload or improperly load yourvehicle, and make sure every passenger isproperly restrained.
In a rollover crash, an unbeltedperson is significantly more likely todie than a person wearing a seat belt.All occupants must wear seat belts andchildren/infants must use appropriaterestraints to minimize the risk of injury orejection.
Do not become overconfident in theability of four-wheel drive vehicles.Although a four-wheel drive vehiclemay accelerate better than a two-wheeldrive vehicle in low traction situations, itwon't stop any faster than two-wheel drivevehicles. Always drive at a safe speed.
Utility vehicles and trucks handledifferently than passenger cars in thevarious driving conditions that areencountered on streets, highways andoff-road. Utility vehicles and trucks are notdesigned for cornering at speeds as highas passenger cars any more than low-slungsports cars are designed to performsatisfactorily under off-road conditions.
Study your owner's manual and anysupplements for specific information aboutequipment features, instructions for safedriving and additional precautions toreduce the risk of an accident or seriousinjury.
Four-wheel drive system (ifequipped)
WARNING
Do not become overconfident in theability of four-wheel drive vehicles.Although a four-wheel drive vehiclemay accelerate better than a two-wheeldrive vehicle in low traction situations, itwon't stop any faster than two-wheel drivevehicles. Always drive at a safe speed.
A vehicle equipped with four-wheel drive(when selected) has the ability to use allfour wheels to power itself. This increasestraction which may enable you to safelydrive over terrain and road conditions thata conventional two-wheel drive vehiclecannot.
For four-wheel drive vehicles, a spare tireof a different size other than the tireprovided should never be used. A dissimilarspare tire size (other than the spare tireprovided) or major dissimilar tire sizedbetween the front and rear axles couldcause the four-wheel drive system to stopfunctioning and default to front-wheeldrive.

The traction grades, from highestto lowest are AA, A, B, and C. Thegrades represent the tire’s abilityto stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade forthis tire is established for atire that is properly inflated andnot overloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heat
buildup and possible tire failure.
The temperature grades are A(the highest), B and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat whentested under controlled conditionson a specified indoor laboratorytest wheel. Sustained hightemperature can cause thematerial of the tire to degenerateand reduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which all passengercar tires must meet under the
Federal Motor Vehicle SafetyStandard No. 139. Grades B and Arepresent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) or36 (2.5 bar) depending on tire sizeand for Metric tires 36 psi (2.5bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.
*Extra load: A class of P-metricor Metric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.
